[0032] Example 1

[0033] This embodiment provides a drug delivery device to solve the problem in the related art that when a large amount of ointment is used, the process of removing the package and squeezing out the ointment is time-consuming, labor-intensive and inefficient.

[0034] See also Figure 1 , Figure 2 A drug delivery device includes: a base 100, a supporting plate 200, and a medicine squeezing assembly 300. The supporting plate 200 can be rotatably mounted on the base 100; a plurality of supporting grooves 240 are provided on the supporting plate 200, and a medicine outlet area 230 is also provided on the supporting plate 200, and the plurality of supporting grooves 240 are all connected to the medicine outlet area 230. The medicine squeezing assembly 300 is used to squeeze the ointment on the supporting plate 200 to the medicine outlet area 230, and the medicine squeezing assembly 300 is arranged on the supporting plate 200, and the medicine squeezing assembly 300 includes a first support rod 310 and a second support rod 320. The first support rod 310 can be slidably mounted on the supporting plate 200, and the first support rod 310 is arranged vertically with the plurality of supporting grooves 240, and the first support rod 310 can abut against the supporting grooves 240. The second support rod 320 is installed on the supporting plate 200 , and the second support rod 320 can slide along the extending direction of the supporting groove 240 ; the second support rod 320 is arranged parallel to the first support rod 310 , and the second support rod 320 can abut against the supporting groove 240 .

[0035] Specifically, when using the drug delivery device of this embodiment, the ointment to be used is stacked as a whole on the supporting plate 200 and placed in the supporting groove 240. The first support rod 310 is adjusted so that the first support rod 310 can contact and squeeze on the ointment to fix the position of the ointment; the second support rod 320 is adjusted so that the second support rod 320 can also contact and squeeze on the ointment. Afterwards, the end of the ointment facing the drug outlet area 230 is disassembled, and the second support rod 320 is controlled to slide in a direction from away from the drug outlet area 230 to close to the drug outlet area 230, and the ointment is squeezed so that the ointment can all flow out into the drug outlet area 230 for use by medical workers. This embodiment can extrude multiple ointments at the same time, which improves the efficiency of the extrusion operation and reduces the workload of medical workers.

[0036] The supporting plate 200 is disposed on the base 100. When using this embodiment, after adjusting the first support rod 310 and the second support rod 320, the supporting plate 200 is controlled to rotate relative to the base 100 until it rotates to a suitable angle, and then the ointment is squeezed out, so that medical workers can use a sterile box to receive the ointment under the medicine outlet area 230 and collect the ointment in one place for subsequent use.

[0037] The support plate 200 can be rotated at any angle relative to the base 100, as long as it is convenient to collect and receive the ointment. Exemplarily, the support plate 200 rotates 90°, that is, the support plate 200 rotates to be perpendicular to the base 100, so that after the ointment is squeezed out, it will not contact the drug outlet area 230, and will directly fall into the sterile box, which is convenient for medical workers to operate, and also avoids the ointment sticking to the drug outlet area 230, resulting in a reduction in the total amount of ointment. In addition, the support plate 200 is rotated to be perpendicular to the base 100, and the ointment will naturally flow downward under the action of gravity, reducing the difficulty of squeezing out the ointment, making the ointment squeezing out more clean and thorough, and improving the utilization rate of the ointment.

[0038] It should be noted that burn ointments are usually provided with an opening at the head, which is sealed by a knob. However, the method adopted in this embodiment is to tear or cut the outer packaging of the ointment from the tail of the ointment. The reason is that if the ointment is squeezed out from the opening of the head for use, on the one hand, the knob must be unscrewed and the sealing film at the opening of the ointment must be removed, which is cumbersome to operate. On the other hand, the opening of the ointment head is small, the speed of squeezing out the ointment is slow, and it is difficult to squeeze out cleanly, which will result in a small amount of waste for each ointment. Since the outer packaging of the burn ointment is relatively soft, the method of this embodiment is adopted, the speed of tearing the outer packaging is fast, the opening is large, the speed of squeezing out the ointment is fast, and the opening is usually close to the diameter of the ointment, and when the ointment is squeezed out, there is less residue in the ointment.

[0039] In one embodiment, for example, Figure 1 As shown, a fixing plate is provided on the supporting plate 200, and the fixing plate is arranged parallel to the supporting groove 240; a first slide groove 210 is provided on the fixing plate, and a first support rod 310 can be slidably installed in the first slide groove 210, and the first support rod 310 can be relatively fixed with the first slide groove 210. The first slide groove 210 is provided on the fixing plate to limit the moving track of the first support rod 310, so that the first support rod 310 can only slide along the first slide groove 210, making this embodiment easier to operate. The first support rod 310 can be relatively fixed with the first slide groove 210, that is, when the first support rod 310 slides to the position where the ointment can be limited, the relative position between the first support rod 310 and the first slide groove 210 is fixed, so that the ointment can be limited, so that when the supporting plate 200 is rotated later, the position of the ointment will not change, which is convenient for the extrusion operation.

[0040] In one embodiment, for example, Figure 1As shown, the first slide groove 210 is vertically arranged, and when the first support rod 310 slides to the end of the first slide groove 210 close to the support plate 200, the first support rod 310 can abut against the support groove 240. The first slide groove 210 is vertically arranged, so that the present embodiment can extrude ointments of different specifications. After the ointment is placed on the support plate 200, the position of the first slide groove 210 can be adjusted to limit and fix the ointment of any diameter, thereby improving the practicality of the present embodiment.

[0041] In one embodiment, for example, Figure 1 As shown, the fixed plate is further provided with a second slide groove 220, and the second support rod 320 can be slidably installed in the second slide groove 220; the second slide groove 220 is arranged in an L shape, the vertical section of the second slide groove 220 is arranged parallel to the first slide groove 210, and the horizontal section of the second slide groove 220 is arranged parallel to the supporting plate 200. The second support rod 320 is arranged in the second slide groove 220, and the moving track of the second support rod 320 is restricted, which further reduces the operating difficulty of this embodiment, and also avoids the second support rod 320 from moving randomly, resulting in incomplete extrusion operation, thereby improving the stability of this embodiment.

[0042] In addition, the second slide groove 220 of the vertical section allows the second support rod 320 to move in the vertical direction until the second support rod 320 contacts and squeezes the ointment. The second slide groove 220 of the horizontal section allows the second support rod 320 to move in the vertical direction into position and then move along the horizontal section to squeeze the ointment, thereby squeezing the ointment out of the outer packaging, making this embodiment easy to use.

[0043] In one embodiment, for example, Figure 1 , Figure 2 As shown, when the second support rod 320 slides to the horizontal section of the second slide groove 220, the second support rod 320 can abut against the supporting groove 240. It is ensured that after the ointment is placed on the supporting groove 240, the second support rod 320 can abut against the ointment when sliding in the second slide groove 220 to extrude the ointment.

[0044] In one embodiment, for example, Figure 2 As shown, two fixing plates are provided and symmetrically arranged at the ends of the supporting plate 200. The two ends of the first support rod 310 and the second support rod 320 are respectively installed on the two fixing plates, so that the force of the first support rod 310 and the second support rod 320 is more uniform, making the structure of this embodiment more stable and reasonable.

[0045] In one embodiment, for example, Figure 2As shown, the medicine discharging area 230 is arranged at the end of the supporting plate 200, and the medicine discharging area 230 is arranged perpendicular to the supporting groove 240; the medicine discharging area 230 is arranged as an inclined surface. The medicine discharging area 230 is arranged at the end and is inclined, and cooperates with the rotatable supporting plate 200 to facilitate medicine discharging.

[0046] Specifically, when the supporting plate 200 is not rotated to be perpendicular to the base 100, the squeezed ointment will fall to the medicine dispensing area 230. The inclined medicine dispensing area 230 can prevent the ointment that falls to the medicine dispensing area 230 from contacting the outer packaging again and causing contamination to the ointment. The inclined medicine dispensing area 230 can also accelerate the ointment to fall. When the supporting plate 200 is rotated to be perpendicular to the base 100, due to the inclined setting of the medicine dispensing area 230, the squeezed ointment will directly fall into the sterile box placed by the medical staff, and will not contact the medicine dispensing area 230, thereby improving the efficiency of the extrusion operation.

[0047] In one embodiment, for example, Figure 1 , Figure 2 As shown, a rotating shaft 250 is provided on the side of the supporting plate 200 close to the base 100, and the rotating shaft 250 and the medicine discharging area 230 are respectively provided on two sides of the supporting plate 200; a through hole is provided on the base 100, and the rotating shaft 250 can be rotatably installed in the through hole, and the rotating shaft 250 can be relatively fixed with the through hole. Through the cooperation of the rotating shaft 250 and the through hole, the supporting plate 200 can be stably and reliably set on the base 100. The rotating shaft 250 is set on the side of the supporting plate 200, and is set on a different side from the medicine discharging area 230, so as to avoid the rotating shaft 250 affecting the operation of the medicine discharging area 230, and improve the rationality and reliability of the structure of this embodiment.

[0048] Example 2

[0049] Based on Example 1, this example further improves the structure.

[0050] In one embodiment, for example, Figure 3 , Figure 4 As shown, the base 100 is also provided with a motor 500, and the output shaft of the motor 500 is connected to the rotating shaft 250. In this way, when it is necessary to control the rotation of the supporting plate 200, it is only necessary to control the motor 500 to start, and the rotating shaft 250 is driven to rotate by the output shaft of the motor 500. After rotating to a suitable position, the motor 500 is turned off. By setting the motor 500, the supporting plate 200 can be rotated without the medical worker having to contact the supporting plate 200. Furthermore, the switch of the motor 500 can be set as an infrared sensing switch, or the switch can be set at the foot, and the motor 500 can be started or turned off by stepping on it. This is not a technical problem for those skilled in the art. In this way, in the process of squeezing out the ointment, the contact between the medical worker and the present embodiment is reduced, and a sterile environment in the clinic is ensured.

[0051] It should be noted that even if the start / stop switch of the motor 500 is set at the foot, and the medical worker does not need to touch it with his hands, when using this embodiment, the medical worker will inevitably contact the first support rod 310 and the second support rod 320 to squeeze out the ointment. On this basis, steps are set at both ends of the first support rod 310 and the second support rod 320, so that when using, the medical worker can use a disposable sterile rubber cap, which is sleeved on both ends of the first support rod 310 and the second support rod 320. After use, the sterile rubber cap can be directly discarded. When used next time, a new sterile rubber cap can be used, so that the medical worker can completely squeeze out the ointment without contact with the present embodiment.

[0052] In one embodiment, for example, Figure 3 , Figure 4 As shown, a counterweight 110 is disposed on the base 100, and the counterweight 110 is disposed at a position on the base 100 away from the through hole. The counterweight 110 is disposed on the base 100 to increase the weight of the base 100, to prevent the base 100 from shaking or tipping over when the supporting plate 200 rotates, causing the supporting plate 200 to tip over, thereby improving the safety of the present embodiment.

[0053] In one embodiment, for example, Figure 3 , Figure 4 As shown, a cutting piece 400 is also provided on the supporting plate 200, and the cutting piece 400 can be slidably installed in the medicine discharging area 230, and the cutting piece 400 can slide in a direction perpendicular to the supporting groove 240. Specifically, a third support rod is provided on the fixed plate, and the third support rod is arranged parallel to the first support rod 310 and the second support rod 320, and the cutting piece 400 can be slidably installed on the third support rod. When it is necessary to cut the outer packaging of the tail of the ointment, the cutting piece 400 is controlled to slide along the third support rod to cut the outer packaging of the ointment, so that the present embodiment is easy to use and the practicality of the present embodiment is improved.

[0054] It is understandable that the third support rod and the cutting piece 400 can be kept in non-contact by the same method as the first support rod 310 and the second support rod 320. That is, when using this embodiment, a sterile rubber cap can also be put on the cutting piece 400 to facilitate clinical operation of medical workers.

[0055] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
